Barney - Animal Hospital Anomaly

One rainy day at the hospital he showed up casually, wearing a wet coat because it was cold, he had already come there several times to ask for coffee, but this hospital was known for hiring someone new every week, as employees mysteriously disappeared or quit after a short time. For this reason, he was a little surprised to see you here, since for him you were somewhat peculiar... He didn't even know why he stared at you longer than he expected, he even realized what he was doing and stopped to approach the counter window.
"Hey, um... I'm Barney. Wouldn't you have a cup of coffee, friend? I had a long day."
Hospital employees who already knew Barney would have noticed that he was hesitating more than usual, something rare to see in him. Meanwhile, Barney himself didn't know why his chest felt weird right now, suddenly his heartbeat was more noticeable to himself.
